Abstract

The invention provides a composite heat treatment method for rapid solid solution and rapid starting from low-temperature alternating aging. The composite heat treatment method comprises a rapid solid solution heat treatment process and a composite heat treatment process for rapid starting from low-temperature alternating aging. According to the scheme, the problems that austenitic stainless steel solid solution and aging heat treatment is poor in quality stability, low in qualified product rate, low in hardness, low in mechanical property, poor in consistency, long in heating time, low in efficiency and low in cost can be solved. And heat treatment equipment is poor in heating reliability, high-temperature components are short in service life, the cost is high, and other special heat treatment technology theories and practice problems are solved.

Description

technical field [0001] The invention relates to the technical field of heat treatment of materials, in particular to a composite heat treatment method of fast solid solution and fast starting low temperature alternating aging. Background technique [0002] The heat treatment principles of austenitic stainless steel (see GB / T1220, GB / T1221, GB / T12773, etc.) Therefore, alloy structural steel is very easy to greatly improve the hardness (or mechanical properties) of the material through quenching and tempering heat treatment methods; while austenitic stainless steel cannot undergo high-temperature austenite transformation under high temperature conditions (only dissolution and precipitation Alloying element strengthening phase), therefore, it is extremely difficult for austenitic stainless steel to greatly improve the hardness (or mechanical properties) of the material through solid solution and aging heat treatment. [0003] The meaning of solid solution heat treatment is: he...
